Truth pluralism is the view that there is more than one truth property. The strong version of it (i.e. strong pluralism) further contends that no truth property is shared by all true propositions. In this paper, I help strong pluralism solve two pressing problems concerning mixed discourse: the problem of mixed inferences (PI) and the problem of mixed compounds (PC). According to PI, strong pluralism is incompatible with the truth- preservation notion of validity; according to PC, strong pluralists cannot find (...) any appropriate truth property for mixed compound propositions, whose atomic constituents are from different domains of discourse (e.g., <sky is blue and chocolate is tasty>). I argue that the strong pluralist is motivated to take the truth predicate in truth-involving universal statements to be deflationary to avoid the two pressing problems. Such a move entails that the truth predicate in the platitude of validity (V) for any argument, it is valid if and only if necessarily its conclusion is true when its premises are all true does not denote any substantive truth property. Instead, it is merely an expressive device to help people generalize instances of (V) to (V). Analogous stories hold for the truth predicate in the platitudes of compound (e.g., conjunction). The upshot is that, the strong pluralist can solve PI and PC by further conceding that mixed compounds are true/false in a deflationary way. (shrink)

Critics of the scope problem that motivates pluralism about truth have argued that it is a pseudo-problem. If the criticism is correct, then truth pluralism is left unmotivated and potentially bankrupt. In this paper, I argue that closely related to the scope problem is another problem, which I call “the scalar problem.” If the property of truth is sensitive to how an agent expresses the truth predicate within a single linguistic discourse and different agents or groups of agents express truth (...) differently within that discourse, then there are different ways of being true within the same linguistic discourse. Given this possibility, even if the scope problem fails, truth pluralism remains fully motivated. Keywords: alethic pluralism, truth, Quine-Sainsbury problem, experimental philosophy. (shrink)
